ИСТИНА

As is known, asteroids are small solid celestial bodies of predominantly silicate composition. At the same time, they are the oldest planetary bodies in the Solar system, the least altered since formation. Despite their vast amount (only in the Main belt are already more than 500 thousand), a relatively small number (less ~1%) of them are classified taxonomically (spectrally). For the reason, heliocentric distributions of different-type asteroids with their specific mineralogy are studied very approximately. A standard processing of spectrophotometric data on several tens of Main belt and near-Earth (NEA) asteroids obtained at Crimean Observatory of SAI MSU (1.25-m telescope with a low resolution spectrograph of in the range of 0.40-0.95 µm, R≈300 in 2003-2010) and at Terskol Observatory (2-m telescope with a low resolution spectrograph in the range of 0.38-0.85 µm, R≈100 in 2015-2017) was carried out. The aim of the work is modeling reflectance spectra of the observed asteroids with measured reflectance spectra of powdered terrestrial mineral samples and proper meteorite analogs from the most complete spectral databases.
